I think 90% of what it says on the container is marketing. Why would it matter if you had 10,000 or 100,000 miles on your car to use a different oil? It would seem logical that a good oil would cover you in both situations, and there isn't really anything you can put in oil to make it better for a 10,000 mile motor opposed to a 100,000 mile motor. That's just how I feel, though.


Castrol and NGK for me.

 

no steve...the oil is good for 15000 miles, meaning not needed to be changed for 15000 miles. not "there is 15000 miles on the car, use this oil" (if i am understnading you correctly)

and i will post those pictures when i get home.

 

I wonder how much more it cost though? so basically change the oil filter and leave the oil

 

they say, thats not even needed.

 

No wait what? no i said i used "regular oil" for 30k miles but changed it ever 2500to 3k miles.

 

when i first got my car, it was pretty much as nasty as this...
like jeffs AM a6 he just built.



after lots of mobile one and that engine restore ----...

i would have to say im satasafied with mobile1

 

well i think most people change there oil prematurely anyways, i know of people that run mobil one up to 8k miles, i always change mine at 3k but most oil is rated to last longer than 3k, Even though its good for 15k miles i dont think i would ever run my oil past 5k.

To those that say why use synthetic over regular oil, there is a noticeable diffrence with synthetics.

 

mobil 1 is one of the only 2 or 3 oil brand that is real synthetic oil..opposed to Castrol...

 

i work at Mobil1 Lube Express we have that. i wouldnt use it and change it every 15k also if your car is under warrenty you cant use it also if you car has a change oil light you cant use it. it says it right on the bottle
